Hg2+光热传感实验的设计与实践
Design and Practice of Experiment on Hg2+Photothermal Sensing
摘要
Abstract
A Hg2+photothermal sensing comprehensive teaching experiment based on temperature signals is designed using problem-based learning(PBL).In this teaching experiment,the CuS nanoparticles(CuS NPs)with high photothermal conversion efficiency are firstly prepared by mechanochemistry-based wet grinding.Then,a novel Hg2+photothermal sensing method is established based on the photothermal signal changes induced by the precipitation displacement reaction between CuS NPs and Hg2+.By integrating the research achievements of"Hg2+photothermal sensing"into the experimental teaching process,the innovative teaching design concept of undergraduate chemistry experiments is explored,achieving the guidance of scientific research thinking in designing innovative university chemistry experiments.It is helpful to systematically and comprehensively train students'ability to discover and solve problems,as well as effectively improve students'comprehensive utilization of basic knowledge and practical innovation ability simultaneously,so as to promote the reform of undergraduate experimental teaching.关键词
